30. (8:26) And Moshe went out from Pharaoh, and entreated Hashem.
31. (8:27) And Hashem did according to the devar Moshe; and He removed the swarms of arov from Pharaoh, from his avadim, from his people; there remained not one.
32. (8:28) And Pharaoh hardened his lev at this time also, neither would he let the people go.
